Children, older adults, and people with other medical
problems may have different symptoms:

Babies may be cranky and refuse to eat. They
may have a rash. They may cry when held.

Young children may act
like they have the flu. They may cough or have trouble
breathing.

Older adults and people with other medical problems may
have only a slight headache and fever.

It is very important to see a doctor right away if you or
your child has these symptoms. Only a doctor can tell whether they are caused
by viral or bacterial meningitis. And bacterial meningitis can be deadly if not
treated right away.

Your doctor will ask
questions about your health, do an exam, and use one or more tests.

Lumbar puncture is the most important lab test for
meningitis. It is also called a spinal tap. A sample of fluid is removed from
around the spine and tested to see if it contains organisms that cause the illness.

Your doctor
may also order other tests, such as
blood tests, a
CT scan, or an
MRI.
